Will Cotton is the artist behind Katy Perry's recent album cover, I really like his paintings but was attracted also to his leaning towers of manmade cake, images of extreme excess.
Taryn Simon is an very interesting photographer whose most recent work forms a book on contraband material confiscated when people entered the US. The resulting images provide a picture of what and why people attempt to smuggle.
Evol is a street artist who works primarily in Berlin, his pieces are very clever with electricity boxes and street furniture sprayed to resemble blocks of flats.
Found the work of Rachel Bee Porter, I really like her fresh take on food photography. Somewhat more appealing to me than the sterilised photos of ingredients for the recent Ikea cookery book.
